Hey check this out:
This video says obsolete in the title which is correct for using fascia as a live part of your character, but as a modeling tool it's still useful.
Here's some simple steps to model the fat:
- Take your skin mesh, delete the hands, feet and head faces.
- Duplicate that mesh, call it "inner"
- Use that workflow in the video above to project the inner layer down onto the muscles/bones using cloth
- Use this script to make a border between your two meshes https://community.zivadynamics.com/d/488-filling-in-space-between-facia-and-fat
- combine, merge vertices and conform normals.
Regarding using wrap3 or similar, consider the following:
If your skin mesh is very high res, you don't necessarily want your fat mesh to be as high res. (large alembic sizes, more attachment points, heavier scenes in general) So: you can imagine perhaps doing step 1-3 above, but then retopologizing your inner layer to get the vertex count down/ have an edgeloop flow that you like.
From there you might want to use wrap3 to get your inner layer projected back out to the skin. The reason you do this is so that you always have the inner and outer layer maintaining a matching topology, so that you can use the make_border() script to quickly build a volume from the two layers.
Hope that helps.
